Heterojunction technology, or HJT, is moving back to the center of this discussion. With its high bifaciality, low temperature coefficient, low LID and PID susceptibility, strong low-light response and long-term reliability potential, HJT is increasingly regarded as one of the most promising platform technologies for the next phase of solar deployment.

For Shanghai Electric Hency Solar Technology Co., Ltd. (“Hency Solar”), the value of HJT is not an abstract technology claim. It must be proven through measurable field performance, disciplined manufacturing and reliable delivery. As the company prepares to meet customers at Intersolar Europe 2026 in Munich, it aims to answer a practical question for global developers, EPCs, distributors and asset owners: which HJT supplier can turn technology advantages into dependable project value?

A stronger-looking market, but harder project decisions

The PV industry has entered a period of deep product convergence. Module formats are becoming more standardized. Power ratings continue to rise. Efficiency figures are improving across mainstream technologies. From a distance, many modules appear to be moving in the same direction.

For project stakeholders, however, procurement is becoming more difficult rather than easier. Falling prices have intensified competition, but they have also increased scrutiny over reliability, warranty credibility, batch consistency and supplier stability. A solar project is not valued by the nameplate power printed on a module label. It is valued by the electricity it produces for over 25 to 30 years.

This is why reliability is returning as a core market concern. Project owners want products that perform under heat, humidity, weak irradiance, high system voltage and long operating cycles. They also need suppliers with stable planning, transparent quality control and financial and industrial strength to support long-term commitments.

In this environment, HJT offers a different value proposition. It is not only a route to higher efficiency, but also a route to more predictable energy yield.

Why HJT: advantages that can be converted into project value

The first advantage of HJT is its low degradation potential. Based on its n-type cell structure and passivation characteristics, HJT has natural resistance to LID, LeTID and PID-related performance losses. For asset owners, this means lower uncertainty in long-term energy-yield modeling and a stronger basis for project returns.

The second advantage is high bifaciality. HJT’s symmetrical cell structure enables strong rear-side power generation. In utility-scale projects, elevated systems, high-albedo surfaces and distributed applications where reflected light can be captured effectively, this can help generate more electricity from the same installation footprint.

The third advantage is the low temperature coefficient. In real projects, modules frequently operate well above standard test conditions. When module temperature rises, output losses can become material, especially in summer, on rooftops and in high-irradiance regions. HJT’s lower temperature coefficient allows it to retain more power under heat, making it relevant not only for desert and tropical markets, but also for commercial and industrial rooftops where module operating temperatures can be high.

The fourth advantage is low-light performance. In Europe and many coastal or humid regions, solar projects often operate under cloudy, rainy, morning or evening conditions. HJT’s high open-circuit voltage and low series resistance help support stable generation under weak irradiance, extending effective generation hours and smoothing daily output curves.

HJT also brings visual and system-level consistency. For C&I rooftops, building-adjacent installations and premium distributed projects, module appearance matters. But the deeper value is engineering consistency: stable workmanship, uniform electrical behavior and traceable quality across batches.

Hency Solar further strengthens this value through product design. Its Creator series adopts high-power HJT architecture, bifacial double-glass design, 0BB technology, high bifaciality and low temperature coefficient. The use of butyl-based sealing helps improve moisture resistance and long-term module durability. At the material level, Hency’s use of silver-coated copper paste also supports reduced silver consumption, an increasingly important consideration as silver costs and supply-chain volatility remain concerns for the PV industry.

Field evidence: proving that HJT is not only a concept

Technology advantages matter only when they can be measured in the field. Hency Solar has used a 5.98 MW commercial and industrial rooftop project in Nantong, Jiangsu province, to evaluate the real operating performance of its Creator 2.0 HJT modules.

Nantong is located in the Yangtze River Delta and has a humid subtropical monsoon climate. It experiences hot and humid summers, cloudy and rainy conditions, seasonal temperature variations and complex irradiance patterns. This makes it a representative environment for testing distributed PV performance under practical operating conditions.

The project uses 625 W Hency Creator 2.0 HJT modules, installed mainly on color-steel rooftops, with part of the system applied to distributed PV carport structures. Monitoring data from July 8, 2025, to June 2, 2026, shows strong operating performance. Over the 11-month monitoring period, the project generated more than 7.1 million kWh of electricity. On May 31, 2026, daily generation reached a historical high of 50,861 kWh. The system also achieved a maximum performance ratio of 93%, significantly above the conventional 80% design reference often used in distributed PV applications.

The data also highlights HJT’s low-light value. During the monitoring period, generation under the 0–400 W/m² irradiance range accounted for 34.19% of cumulative electricity output. Even in the extremely weak 0–100 W/m² range, generation accounted for 7.96% of cumulative output. The 100–200 W/m², 200–300 W/m² and 300–400 W/m² ranges contributed 8.72%, 8.44% and 9.07%, respectively.

To further evaluate low-irradiance performance, Hency Solar also conducted comparative field testing of HJT and TOPCon modules in typical climate regions including China’s Hainan, Turpan, Yinchuan and Zhangbei. In the 0–400 W/m² irradiance range, HJT modules showed generation gains of 1% compared with TOPCon modules.

These results demonstrate that HJT’s advantages are particularly meaningful when assessed across real operating windows rather than only under standard test conditions.

Lower-energy manufacturing and lower-carbon value

HJT also has value beyond module performance. Its manufacturing process uses lower-temperature steps than some conventional crystalline silicon cell technologies, which can help reduce energy consumption during production. As customers in Europe and other international markets place greater emphasis on product carbon footprints, supply-chain transparency and lifecycle emissions, this characteristic gives HJT an additional strategic advantage.

For Hency Solar, low-carbon innovation is not only a product attribute. It is part of the company’s long-term positioning: to provide high-efficiency solar solutions that support the global transition to cleaner energy while improving project-level economics.

Why Hency Solar: reliability as a measurable supply capability

HJT is a demanding technology. It requires precise passivation control, stable process windows, material compatibility, advanced metallization, strict encapsulation design and disciplined quality management. The challenge is not simply to produce an HJT module. It is to produce HJT modules reliably, repeatedly and on a commercial scale.

This is where Hency Solar’s background becomes important. Backed by Shanghai Electric’s industrial manufacturing and energy-equipment expertise, Hency Solar combines advanced HJT technology with long-cycle project delivery capability and stable supply-chain management. This gives the company a stronger basis for stable production planning, supply-chain coordination, quality systems and long-term service commitments.

For overseas customers, reliability has three meanings.

The first is quality. Hency Solar emphasizes process control, incoming material management, product testing, batch traceability and long-term reliability verification. Its Creator series is designed around anti-PID, anti-LID/LeTID, bifacial generation and long-term output stability.

The second is delivery. In a market where project schedules are increasingly tight, customers need suppliers that can plan production consistently and support predictable shipment. Stable delivery is not a sales promise; it is an operational capability.

The third is service. Hency Solar aims to support customers with technical documentation, project analysis, application guidance and after-sales response, helping translate HJT’s technical strengths into project-level results.

The company’s values — perseverance, low-carbon innovation, heartfelt performance and customer success — are reflected in this approach. For Hency Solar, long-termism means delivering not only advanced modules, but also stable performance, reliable cooperation and measurable value.
